Set up just like an ollie with with your back foot a little more on the toe side of the tail. Pop the tail and scoop the board around. After you've made the 180 make sure to turn and be ready to ride. Many people land the trick, but then it shoots out from under them because the didnt anticipate landing switch. Then to get this trick higher, try popping the board (instead of scooping) and then make the rotation later. Its harder but it also gets higher.
